PUMP ATTACHMENT.

To all whom it may concern: 7

Be it known that I, JOHNFRE a citizen of the United States, residing atGuide- Rock, in the county of Webster, State'of Nebraska, have inventedcertain new and useful Improvements in Pump Attachments;

and I do hereby. declare the following to be a full, clear, and exactdescription of the nozzle or be directed through a branch pipe anddelivered at any desired point.

\Vith the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claims.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in which- Figure 1 is avertical longitudinal section of a portion of a pump having theattachment associated therewith, the pump plunger being shown at thelimit of its down stroke and the three-way valve of the attachment setto effect the discharge of the water through the pump nozzle. Fig. 2 aview similar to Fig. 1 showing the pump plunger at the limit of itsupstroke and the threeway valve of the attachment set so that the waterwill be discharged into a branch pipe. Fig. 3 a view in elevation of theattachment on an enlarged scale, and Fig. 4; a section on the line 4 tof Fig. 3.

Referring to the drawings 10 indicates the barrel of the pump which hasa suitable section removed therefrom in its length and substituted forthis section is the tubular member 11 of the attachment, said memberSpecification of Letters Patent.

Application filed December 9, 1912. Serial No. 735,757.

11 being secured to the adjacent ends of the resultant barrel sectionsby means ofiT-joints '12. Secured to the T-joints l2'respectively arethe terminals of a branch pipe line 13 and disposedin this branch pipeline '13 is a three-Way valve 14 operated by a handle15 and serving todivert the water passing through the branch pipe line 12 to a pipeIatented Nov. 2, 1915.

line 16. Mountedin the lower end of the pump barrel 10-is' the usualcheck valve 17- and sl1dable in the barrel 10 between the check valve 17and the adjacent T-joint 12 is i the usual plunger 18 secured to one endof a plunger rod 19. This rod 19 extends upwardly and is connected atitsupper end to the usual pump operating handle (not shown). The plungerrod 19 includes a section 20 upon'which is mounted a cup plun ger 21adapted for movement in the tubular 1 member 11.

By this construction it will be apparent that as the plunger rod 19 isreciprocated in l the usual manner the upstroke of the plun ger 18 willdraw the water above vthe valve 17, while the down stroke of saidplunger will close the valve 17 and force the water through the plunger18 into the barrel 10 thereabove. Continued reciprocation of the plungerrod will cause the water to fill the entire space between the cupplunger21 and the valve 17 so that upon each down stroke of the cup plunger 21the water will be forced into the branch pipe 13 at the lowermostT-joint 12. If the valve 14. is set as shown in Fig; 1 the water willcontinue through the branch pipe 13 and be delivered to the barrel 10and section 11 above the cup plunger 21 and finally discharged throughthe pump nozzle. If the valve 14 is set as shown in Fig. v2 the waterwill be diverted through the pipe 16 as will be obvious.

What I claim is In a pump, the combination of a pump barrel, a valvedplunger movable in said bar= 'rel at points respectively above and belowthe limits of movement of the non-valved plunger and further having. itsupper end In testimony whereof, I affix my signature, in the presence oftwo Witnesses.
